Our offers for municipal wastewater treatment plants

Microplastic analysis as a comprehesive service

We offer a comprehensive service from standardized sampling to detection and reporting.

Once an appointment has been made, Wasser 3.0 takes care of the rest. Our microplastic analysis is based on fluorescence markers and enables fast, cost-effective, comparable, and scientifically validated microplastic monitoring.

Wastewater Treatment Plant

Municipal wastewater treatment plants are a hotspot for microplastic emissions to the environment.

Although wastewater treatment plants can remove most of the microplastics within three treatment stages, they are still a significant source of microplastics in the environment due to the residuals and high volumes of wastewater

Therefore, the revised EU Urban Wastewater Directive (Directive 91/271/EEC) introduces the following mandatory routine measurements of microplastics in the wastewater treatment plant effluent:


  • Plants with more than 100,000 population equivalents (p.e.) must take samples at least twice a year, with a maximum interval of six months between samplings.
  • Plants with more than 10,000 p.e. must take samples only once every 2 years.
  • Wastewater treatment plants (>100,000 p.e.) must also monitor for the presence of microplastics in sewage sludge.

Everything from a single source

Take advantage of our all-round carefree package. Wasser 3.0 offers a standardized service for collecting data on microplastic pollution in municipal wastewater.


On-site sampling

  • We have developed a mobile sampling unit to enable fast and comparable sampling for microplastic detection.
  • Standardized, validated, and cross-validated.
  • Comprehensive and comparable data.
  • Flexible sampling times.


Rapid microplastic detection thanks to innovative fluorescent markers.

Our detection technology is based on selective fluorescent labeling of microplastics, making it fast, reliable, and cost-effective.

  • Validated and cross-validated method.
  • Proven in long-term studies on wastewater treatment plant effluent (> 200 samples).
  • Proven in 4th stage treatment plus long-term studies (microplastic and micropollutant removal).
  • Unit of measurement: microplastic particles (MP) / liter [MP / L].


Required conditions:

  • Access to the wastewater treatment plant.
  • Power supply.
  • Access to outlet manhole / outlet.
  • Access to tap water.

Understanding of water vs reality

Get up in the morning, drink a glass of tap water, make coffee or tea, take a quick shower, brush your teeth, do your laundry, cook and so on. We need water - for everything. Water is a fundamental and natural part of our lives. Without clean water, we cannot live, we cannot survive. But the image of crystal clear water is becoming clouded. More and more pollutants, more bad news. How should we deal with water as the basis of life in the future?

EU Urban Wastewater Directive adopted in April

The EU Urban Wastewater Directive (UWWTD for short) was adopted by the European Parliament at the beginning of April 2024. Among other things, it aims to remove microplastics and micropollutants from our wastewater and increase the efficiency of wastewater treatment plants in a cost-effective manner. The keywords here are also: Resource conservation, water quality, circular economy, energy efficiency and sustainability. But what is the roadmap for this? We have taken the Wasser 3.0 perspective.

Our blog about water without microplastics

We want to stop the uncontrolled pollution of our water with microplastics and micropollutants. In our blog posts, we describe step by step why it is high time to do so and how we want to achieve this. We focus on current information and always keep an eye on the latest opinions and curiosities.
